Y., assignor to Wilv son-J ones Co., ChicaMassachusetts go, Ill., a corporation of Application July 5,1947, SerialNo. 759,106 1 Claim. (C1. 281-29) for detachably interlocking with aloose leaf More specically the invention has for binder. an object theprovision of spaced and fixed keepers simultaneously adapted to beinitially received within relatively enlarged openings of spacedcompound slots in a loose leaf binder whereby spaced sides ofrectilinear openings of the coml5 pound slots are awaiting to straddlethe keepers and be arranged under overhanging lips thereof for slidablyinterlocking with the keepers upon shifting the binder longitudinallythereof after which liftable locking means carried by the binderautomatically operates to cooperate with one of the keepers to precludedisplacement of the binder relative to the portfolio. A further andspecic object is concerned with automatically retractable detent meanscarried by the loose leaf binder and overhanging a major portion of oneof the compound slots thereof and adapted to be automatically elevatedon mounting the binder on the spaced keepers xedly carried by theportfolio.

Another object comprehends the utilization of a conveniently accessiblemanipulator for elevating one end of the tiltable detent means to permitslidable displacement of the binder relative to the portfoliopreparatory to detaching the former from the portfolio.

Advantageously fastened to the portfolio P is the relatively sturdyleather wall I 0 dening with the outside leather body II of theportfolio the storing compartment I2.

Anchored by sp-aced rivets or keeper means I4 tothe wall Il) (Figs. 2and 4) is the leather strip or backing I5. Specifically each rivet I4 isprovided with an annular flange I 6 adapted to be seated on .the leatherstrip I5.v About the shank of each rivet I4 and held against thecompartment or pocket wall II] by head I'I of the rivet is the annularwasher I8. -By the present arrangement Vit is apparent thatv the stripI5 is firmly clamped against the pocket wall IU by an annular flange I6and a companion annular washer I8.

Integral with annular and overhanging flange I6 and extending upwardlytherefrom is the reduced web lI9 (Fig. 8) having the spaced rectilinearsides 20 and defining with the overhanging lips 2| of the annular headas of the rivet I 4 spaced channels, grooves ortracks 23.

The circular head 22 of the studs or rivets Ill are smaller than theenlarged expanded and spaced circular openings 25 at corresponding endsof compound slots generally each denoted 26 and each having a reducedand rectilinear opening 2l in communication with its companion circularopening 25. Preferably the compound slots 26 are disposed in the bottomarcuate plate 28 of a conventional ring type loose leaf binder generallyindicated RTB for removably holding a stack of perforated sheets ofpapers (not shown) and adapted as is customary to be opened and closedby operating the triggers29. Y

With the enlarged or expanded openings 25 means I4 and moreparticularlythe heads 22 thereof, the spaced portions 3|) constitutingthe rectilinear sides of the reduced openings 21 of the compound slots25 are in alinement with spaced gaps 23, and hence the binder may beslidably and bodily displaced in the direction of the arrow 3| (Fig. 5)whereby sides 3|) of the compound slots move 4under lips 2| and`simultaneously straddle the webs or intervenors |9 of the keepers |4,thus interlocking therewith. However when the ends 32 of the restrictedopenings 21 are near the keeper means, the binder is locked againstlinear displacement due to the action of the self retractinglockingfdetent generally indicated D comprising a relatively :flat and flexibleleaf spring 35 and the superimposed cold rolled and non-flexible bar 'orlever 3B provided with a fixed manipulator or button 31 normallyprojecting in part through opening 38 in the upper arcuate cover plate39 of the loose leaf binder RTB.

Lever 36 is secured to one end of the leaf spring 35 by rivet 40 and theother end ofthe leaf spring 35 is anchored to the bottom wall 28 of thebinder by the rivet 4|. 'Normally spring 35 holds the detent retracted,that is, substantially horizontal as shown in Figs. r6 and 7 and againstthe wall 28 `of .the binder to :permit the front end FE of the detent tooverhang the adiacent expanded opening .2'5 .and an associatedcommunicating reduced opening 21 `of the compound slot '26.

Upon insertion of the heads 22 of the spaced keeper means |14 'into theenlarged openings 25, one of the heads 22 automatically tilts the detentD (Fig. causing the frontend FE to be automatically raised therebycausing the other end BE thereof to 'be biased or tilted downwardly intorelief opening 42 in the hollow wall 28. Or i-n other words, detent Dunlocks automatically. As the binder is moved in the .direction of arrow3| and under the lips 2| of heads 22 of the spaced keeper means, detentD automatically is urged to assume a substantially 'horizontalpositionvdue to the retractive action of the lea'f spring 35.Consequently when the head 22, tilting the ydetent, clears the front endFE, the detent automatically and fully retracts and drops into 'the pathof the adjacent keeper, thus -constituting a stop (Figs. -6 and 7)-precluding 'slidable -displacement of the binder relative to theportfolio, that is, the binder is locked against Aslidable -displacementand against removal from Vthe portfolio. To detach the binder from theportfolio, manipulator 31 is depressed as shown in iFig. 6 by the dashand dot line position, 'thereby elevating the forward end FE of thedetent D above the elevation of the companion head 122' of theassociated keeper means which Ais then vadapted to be slidably displacedto unlock from the walls 30 and eventually the heads of the spaced-keeper means arrive to be within the spaced Vopenings 25 at which timethe binder may be lifted and be disengaged therefrom -or -in-other words`from the portfolio.

In the form according -to Figs. 19 :to vl2, the locking detent D' ischaracterized by a Vmetal leaf spring 5|] -having `end BE' secured by-rivet 5| to the outside face of the arcuate `bottom '28 of the binderand its intermediate portion thereof is disposed longitudinally Aacross:the enlarged opening 52 in the bottom wall '28 while its free end FE isnormally seated on the 'spacedstop lips 53 at the junction of the'opening 52 and the lcommunicating irectilinear opening 254 falso in thebottom wall 28. Spring xedly carries the knob or manipulator projectingthrough and above opening 56 in the cover 39 of the binder.

In Fig. 10, the binder may be considered locked to the portfolio as therectilinear sides of the slot 54 are interlocked with adjacent head 22of one of `the spaced keeper means while the head of the other keepermeans is interlocked with side walls as 3|] of the opening 21 at theother lend of the plate 28, as is well understood, at which time thefree end FE' of the normally depressed detent D is in line with anadjacent head 22 of the keeper means |4 and acts as a stop to precludeslidable displacement of the binder yrelative to the portfolio eventhough, as in the embodiment according to Figs. 1-8, the binder isinterlocked with the keeper means.

To unlock detent D', the operator merely lifts manipulator 55 upwardly,causing end FE to rise appreciably above :the adjacent head 22, thus1inlocking .part the binder :and the latter may be slidably .moved tothe right relative to the 'portfolio and eventually heads A22simultaneously reach the enlarged openings ,'25 and A52 (Fig. 11B) andthe 'binder ymay 'be .lifted from the portfolio. rillnereafter uponremoval of the linger pressure from manipulator 55, leaf vspring 50retracts against l.the vstop lips 53 awaiting to :be :again raised :byone of the 'keeper means 22 when 'the binder is ,again attached to theportfolio. Of course the operator ymay unlock detent D from theladjacent keeper by lifting 'the detent 11pvvardly -by a nger 'insertedunder end opening `ful in the pocket wall 10. In other aspects lthesemsediment according to Figs. 9--12 is along the lines of the formshown in'Figs. Y1-'8 v'and in all the forms disclosed, the :middle ring`MR llwhen attaching the binder is rst lined up vwith the datum line orindex means 5U for automatically positioning the spaced keepers `inalinement with the (circular openings 25 of the vcompound slots 2:6 forsimultaneous and Aexpeditious reception thereby.

Briefly -recapitulating in all the forms disclosed a normally retractedIlocking detent overhangs 'a major portion .of an elongated and compoundslot 26 `for example, in Fig. 1l defined by -the communicating openingsl52 and A5.4 and in 4 by the-communicating openings -25and 2H. In veachcase, the detent is adapted Ito be automatically tilted-on'mounting thebinder .on the spaced-keepers |14, that is, -when the llatter arereceived by the enlarged portions I25 of the compound slots. By suchaction one of the keepers tilts or elevates one end of the detent andholds .the latter elevated iuntil=corresponding ends as S2 of thenarrownopenings 2-1 have reached the spacedkeepers at which time :thedetent means snaps back to be in alinement with or in the path of an.adiacent keeper, thus ,acting .as stop means to prevent longitudinaldisplacement of .the binder relative tto .the portfolio.

Various changes may be made in details .of construction and arrangementfof kparts without departing from .the spirit of the vinvention orsacricing vany yof 1the advantages thereof `inherent therein.
